Offering you hugs. I am deep into 'motherly' attachment with my T. However, she hasn't said any of the things yours has. She is just as much 'with me' as she was before we started talking about the 'mom' stuff. She even told me that is what she was doing, and what I needed and she would be there with it through every step of the way and that I would eventually wean myself from her but right now what I feel I need is what I need and it's okay.

I'm sorry you are having such a hard time and your T is being cold. I hope you can find relief soon or that she'll be open to an honest/candid conversation about how you're feeling and be able to offer you ways to cope as you struggle through this change.
